Duct Leakage Test in Harrison town, NJ

Guarantee your HVAC system runs efficiently and adheres to local requirements with quality duct leakage test in Harrison town, NJ. Our certified technicians measure and identify ductwork air leaks, assisting homeowners and builders in boosting comfort, limiting energy waste, and maintaining state compliance.

Why Duct Leakage Test is Important In Harrison town, NJ

States and municipalities have adopted the 2015 IECC, International Energy Conservation Code for single-family buildings and the 2018 International Energy Conservation Code for multi-family buildings. The change will present notable implications for home builders and HVAC contractors active throughout the state. A Duct Leakage Test as well as the required Blower Door Test must now be performed on new or remodeled homes following the 2015 regulations. Did you know that ducts are frequently the biggest contributors to home air loss in Pennsylvania, New Jersey, and Delaware? Leaked air can drive up energy bills, put extra stress on your HVAC system, and circulate dust and insulation throughout your living space. This makes duct leakage test a crucial step for maintaining comfort in new and old homes alike. Continue reading to learn why duct leakage test is valuable and how it benefits you.

What Our Clients Say

How a Duct Leakage Test Is Conducted

To set up a duct leakage test in Harrison town, NJ, the technician begins by sealing all supply and return registers, leaving only the air handler or main return open. A specially calibrated fan, known as a duct blaster, is then attached to the opening. The purpose of this fan is to depressurize the duct system, creating the ideal conditions to identify where air is escaping.

The duct blaster works in sync with a precision pressure sensor to assess airflow and find duct leaks without disturbing your living space. A duct leakage test — sometimes identified as a duct blaster test — shows where your ducts lose air, helping you plan the right sealing approach.

duct leakage test is simple, clean, and minimally invasive for residents. Most tests in Harrison town, NJ are completed within 30 to 60 minutes, and the improvements can benefit your home’s comfort and efficiency for years.

How to Measure Duct Leakage

Duct leakage is quantified in cubic feet per minute (CFM) for each 100 square feet of conditioned living space. Your technician uses a nanometer to identify subtle pressure differences, helping determine how much air is leaking from the ducts. Understanding this number enables you to recognize problem areas, consider efficiency improvements, and verify that your home meets local energy code requirements in Harrison town, NJ.

Cost of Excessive Duct Leakage

If you’re seeing higher energy bills, irregular heating or cooling, or frequent HVAC malfunctions, duct leakage may be at fault. According to ENERGY STAR, duct leakage causes homeowners to lose 20%–30% of their conditioned air on average. Outside hot or cold air leaking into your system puts extra strain on your HVAC unit, raising energy bills and decreasing comfort.

Overworked equipment also contributes to repeated breakdowns and pricey repairs. Proper duct sealing helps sustain your HVAC system’s long-term condition, increasing its operational lifespan and decreasing maintenance requirements.

Duct leaks can also cause dust, mold spores, and excess moisture — along with other contaminants — to infiltrate the duct system. This can make allergies more severe, reduce the quality of indoor air, and produce costly structural harm behind walls or ceilings as time progresses.

How to Properly Seal Ductwork in an Old Home

The 2015 IRC/IECC requires all newly constructed homes to have fully sealed ductwork with modern, energy-saving materials such as mastic, foil tape, and insulation. But what about leaks that are hidden far behind walls or ceilings?

Aerosol sealing technology (AeroSeal) allows technicians to seal leaks located inside inaccessible parts of ductwork. To carry out the procedure, technicians seal off all vents except one access point. The HVAC system is isolated, and a machine is linked to the duct system. It pressurizes the ducts and circulates a fine aerosolized sealant that locates and fills tiny leaks beyond the reach of typical sealing.

This method works very well for small to medium leaks. However, larger openings may still need to be sealed manually with mastic and tape. Technicians perform a duct leakage test both before and after aerosol sealing to determine how much leakage has decreased and confirm the treatment worked.

Common Areas of Duct Leakage

The most usual spot for duct air leakage is the joints. Ductwork is composed of various metal pieces pressed together using tight fittings and metal bands, but these seals are hardly ever fully airtight.

As your HVAC system runs through seasonal heating and cooling, the ducts experience ongoing expansion and contraction. Over time, this movement causes the joints to loosen, opening gaps and leaks — making a duct leakage test beneficial for both new and older homes in Harrison town, NJ.

Many energy auditors detect leaks by checking the duct surfaces by hand and using a small tool to measure joint gap width. If your duct system lacks proper sealing with mastic and approved tape, there is a high chance that leakage is taking place.

What Is an Acceptable Amount of Duct Leakage per Energy Code?

To achieve a passing duct leakage result, your system has to measure below 4 CFM per 100 square feet with the air handler installed, or 3 CFM per 100 square feet without the air handler. For new construction, a duct leakage test must be passed before any home is eligible to receive an occupancy certificate.

If your home in Harrison town, NJ doesn’t achieve a passing duct leakage score, you’re likely overspending on heating and cooling — and putting extended strain on your HVAC unit. Meeting the 3–4 CFM requirement is essential not only for code compliance but also for protecting your home’s energy efficiency and comfort.

Your technician will also advise you on the best ways to address leakage issues so you can pass the test, reduce utility bills, and enhance your home’s efficiency.

The Duct Leakage Test Steps Explained

A duct leakage test begins by ensuring all ducts and registers are sealed with duct mask tape on both the supply and return sides.

After the registers are sealed, we hook the duct tester to the HVAC unit or a main return.

The ducts are then lowered to a depressurized level of 25 Pascals. With the system at that pressure, the nanometer is used to read the duct leakage.
